-
Treatment with commercially available dupilumab within 12 months, participation in prior dupilumab clinical trial, or discontinued dupilumab use due to adverse event.
-
Patients who are treated with intranasal corticosteroid drops; intranasal steroid emitting devices/stents; nasal spray using exhalation delivery system, such as Xhance™, during screening period.
-
Patients who are on intranasal corticosteroids (INCS) spray unless they have received stable dose for at least 4 weeks prior to Visit 1.
-
Patients who have undergone sinus intranasal surgery (including polypectomy) within 6 months prior to Visit 1.
-
Patients who have taken:
- Biologic therapy/systemic immunosuppressant to treat inflammatory disease or autoimmune disease within 5 half-lives prior to Visit 1
- Any investigational mAb within 5 half-lives prior to Visit 1
- Anti-IgE therapy (omalizumab) within 4 months prior to Visit 1. - Treatment with a live (attenuated) vaccine within 4 weeks prior to Visit 1
-
Leukotriene antagonists/modifiers unless patient is on a continuous treatment for at least 30 days prior to Visit 1.
-
Initiation of allergen immunotherapy within 3 months prior to Visit 1 or a plan to begin therapy or change its dose during the screening or treatment period. - Patients received SCS during screening period. - Either intravenous immunoglobulin therapy and/or plasmapheresis within 30 days prior to Screening Visit (Visit 1).

- Primary Outcome Measures
Name Time Method Change from baseline in sinus opacifications assessed by computerized tomography (CT) scans using the Lund Mackay (LMK) score at Week 52 Baseline to Week 52 LMK total score is based on assessment of the CT scan findings for each sinus area. The extent of opacification is rated between 0 (normal) to 24 (total opacification).
- Secondary Outcome Measures
Name Time Method Dupilumab concentration in serum over time Baseline to Week 52 Change from baseline in sinus opacifications assessed by CT scans using the LMK score at Week 24 Baseline to Week 24 LMK total score is based on assessment of the CT scan findings for each sinus area. The extent of opacification is rated between 0 (normal) to 24 (total opacification).
Change from baseline in monthly average total symptom score (TSS) derived from the Nasal Symptom Diary at Week 24 and Week 52 Baseline to Week 24 and Week 52 TSS ranges from 0 to 9. Higher scores on the TSS indicate greater symptom severity.
Change from baseline in visual analog scale (VAS) rhinosinusitis at Week 24 and Week 52 Baseline to Week 24 and Week 52 VAS score ranges from 0 ('not troublesome') to 10 ('worst thinkable troublesome').
Change from baseline in University of Pennsylvania smell identification test (UPSIT) at Week 24 and Week 52 Baseline to Week 24 and Week 52 The UPSIT score ranges from 0 to 40, with 40 being the best possible score.
Percent change from baseline in total IgE in serum compared to placebo over the 52 weeks treatment period Baseline to Week 52 Incidence of treatment-emergent anti-drug antibodies (ADA) to dupilumab over time Baseline to Week 64 Enter Endpoint Secondary
Change from baseline to Week 52 in three Dimensional CT volumetric measurement of the paranasal sinuses Baseline to Week 52 Change from Baseline in the monthly average anterior/posterior rhinorrhea score from the Nasal Symptom Diary at Week 24 and Week 52 Baseline to Week 24 and Week 52 The rhinorrhea scores are scored from 0 ('No symptoms') to 3 ('Severe symptoms').
Change from baseline in endoscopic NPS compared to placebo at Week 24 and Week 52 Baseline to Week 24 and Week 52 The total nasal polyps score (NPS) is the sum of the right and left nostrils, ranging from 0 (no polyps) to 8 (large polyps causing complete obstruction).
Change from baseline in 22-item sino-nasal outcome test (SNOT-22) total score at Week 24 and Week 52 Baseline to Week 24 and Week 52 SNOT-22 is a patient-reported outcome (PRO) questionnaire. Score ranges from 0 to 110 with higher score indicating greater rhinosinusitis related health burden.
Incidence of treatment-emergent adverse events (TEAEs) or serious adverse events (SAEs) Baseline to Week 64 Proportion of patients who receive systemic corticosteroids (SCS) and/or undergo/plan to undergo surgery for AFRS during the planned study treatment period Baseline to Week 52 Change from baseline in monthly average nasal congestion/obstruction score from the Nasal symptom Diary at Week 24 and Week 52 Baseline to Week 24 and Week 52 The nasal congestion/obstruction scores are scored from 0 ('No symptoms') to 3 ('Severe symptoms').
Change from baseline in the score of decreased/loss of smell using the Nasal Symptom Diary at Week 24 and Week 52 Baseline to Week 24 and Week 52 The decreased/loss of smell scores are scored from 0 ('No symptoms') to 3 ('Severe symptoms').
Percent change from baseline in fungal-specific IgE in serum compared to placebo over the 52 weeks treatment period Baseline to Week 52
